Plot of \(|\varepsilon |/\sigma\) vs \(\sigma\) for the points shown in Fig 1b The blue and orange lines are defined by \(|Z| = |\varepsilon |/\sigma = 2\) and \(|Z| = |\varepsilon |/\sigma = 3\), respectively. Though both the turquoise and green points are sampled from a normal distribution the NLL are different (2.33 and 3.39, respectively). Since the points are sampled from a normal distribution, the distribution of |Z| values also follow a normal distribution with a standard deviation of 1
